I'm trying to setup a form where some fields needs to be hidden depending on the user role. I'm doing this in my own module using hook_form_FORM_ID_alter. No problem with common text, email or link fields (e.g. $form['field_companyname']['und'][0]['value']['#type']='hidden'). But for an image field or a multiple value file field the usual way won't work.
Anybody can give me a clue?
I think your going about this the wrong way. Since your limitation is based on roles you can just use the permissions system. Check out field permissions module.
I recommend you to use #access for the element instead of just hiding the field.
For field company name it will go like this:
$form['field_companyname']['#access'] = FALSE;

Let's say I need to print the full name of a person. What I originally did was to separate the first name and last name into two elements and placed them side by side since they needed different styling (this is just an example):
Lastname, Firstname
However, I found out after that I can't actually make their width dynamic because the developers made an effort not to allow it. So now I'm wondering if I can present the name with two different styles inside one element. Is this possible? How would I accomplish that? I hope you can help, thanks!
Okay so apparently you can. All you need to do is setup the markup attribute on the text field.

In Drupal 7, is there a way to change the standard edit form for a content type based on a certain content?
For example:
I have a content type with a checkbox...once it it checked and the form is saved, I do not want this checkbox to be visible anymore...therefore based on the checkboxes value in the Database I want to hide form fields when showing the form.
I am building a small specific project site, where a company wants to add projects, and their customers are supposed to follow certain steps (upload some content, provide information etc.), and also should be able to check off certain requirements, and once these are checked off, they should not be visible/editable to them.
Also the displayed form fields should depend on an user's role, and then FURTHER be limited depending on the content's database entries.
Is there a module, which could achieve this behaviour? "rules" and "field/permissions" come close to what I need, but are not sufficient. Or did I just miss the option to change a form field's accessibility based on conditions?
What I need is some place to define a logic like "IF (VALUEOF(CHECKBOX_1) == TRUE) THEN DO_NOT_SHOW(CHECKBOX_1)"
hook_form_alter is the way to do this, as explained by Mihaela, but what options do you have inside that function?
If you want just to disable field (it will be visible, but user can't change it) you can do it like this:
$form['field_myfield']['#disabled'] = TRUE;
And if you want it to be hidden, but to keep value it has before editing the way to do that is:
$form['field_myfield']['#access'] = FALSE;
I.e. hiding it (somewhere I saw someone suggesting that):
hide($form['field_myfield']);
really hides the field, but after that, when form is saved this field has empty value, validation fails, etc, so that's not a good way to do this. Hiding makes sense only if you want to print separately that field later, at some other place.
function your_module_form_alter(&$form, &$form_state, $form_id){
switch($form_id) {
case 'nameOfTheNode_node_form':
//your code here. check the value from from_state.
break;
}
}
In this case, I use module Conditional Fields https://www.drupal.org/project/conditional_fields
For example: If my Dependees field has a value, Dependent field can be visible/invisible, enabled/disabled, required/optional, checked/unchecked
I'm creating a multilingual Drupal site and trying to implement a search function, that only displays results in the current language, that the user is viewing the site through.
Using Drupals own searchfunction at /search/node it is possible to select which language to search for through the "Advanced search" options, and it works perfectly. However, I dont want to expose these language selectboxes, I just want it to only search in the current language automatically.
What's the best option to do this?
I have one solution where I create a hook_form_alter function, that sets the #default_value in the language selectboxes to the current language, and then I hide the whole "advanced options" with in css. This doesnt seem very right though.
I think the most clean solution would be to hook into Drupals form-processing process and append ex "language:en" to the input text, but I cannot get this to work.
Does anyone know if it is possible via one of the Drupal form related alter functions, to get a hold of the input text and alter it before drupal does its final processing of it?
To answer your question specifically, while using 'hook_form_alter', you have a referenced variable called '$form_state'. This stores the values in the form, and any change there will be passed further.
Also,
I think setting a default value and hiding the field is a good solution as any, only, if you are hiding it you should do it server side, while altering the form. The same field you are setting the default value to. like this:
$fieldname['#type'] = 'hidden'.
I'd like to know how to override/change the default fields in user profile such as: button Save, name, timezone etc.
I'd like to alter, delete('cause i don't need them) some of them.
To alter the user profile i use the hook: hook_form_alter using which i managed to add my own fieldds to user profile. But now i want to alter the default fields. How can i do it?
It is possible with the hook_form_alter, though it is better to use hook_form_FORM_ID_alter!
To be able to alter the form you need to know the structure of the arrays, the easiest way to get to know this is by installing the Devel module. Then you can view the structure by placing dpm($form); inside your alter function.
You can use this function on your custom module or in your theme (in template.php file).
Usually user profile form_id is user_profile_form. A simple example would be:
function mymodule_form_user_profile_form_alter(&$form,$form_state,$form_id){
$form['timezone']['#access'] = FALSE; //remove the "timezone" field from the form (default value is still saved)
$form['field_somefield']['#weight'] = -50; //move the field up
$form['actions']['submit']['#value'] = t('Add this content now'); //change the submit button text
}
For a good tutorial see the Lullabot tutorial here (is for drupal 6 but works the same way for d7!).

I have a program built with VBA, in access.
I have a form with the field chDate and I need to get the value of the field in a module file named Global (not class module).
I tried to access it but I think I get empty value, string. not error.
I'm no expert with VBA, its new to me (I have experience with VBS).
Can someone please help me and tell me how can I access the value of a form field via module file?
Thanks!
If you can provide some sample code, it might help us in trying to get you a solution.
Here's what might work:
Dim an object as an instance of your form, and set the instance to a new instance. These two lines will do that (assuming the form is called frmForm)
Dim theForm as frmForm
Set theForm = new frmForm
then Show that Form:
theForm.show
The form will get the focus, so you can populate the fields. At that point, once the form is hidden, your code should be able to pull the field as such:
var1 = theForm.txtFormField.Text
However, if you unload the form in code, all variables directly tied to the form will be lost. In that case, you might want to follow Oneide's example, and set a global variable to the value of the form field. You can do this in one of the form's event handlers.
Let me see if I can recall my Access days. In your global module you should access the form field be prefixing the form name i.e.
var1 = Form1.txtFirmField.Text
As far as I know, you're trying to get the data the wrong way.
Anytime you would try to get your form data, from a standard module, your form probably will already be closed or, if you're not opening it as a restricted window, the value will not be ready yet.
Anyway, if you could get pass through all the difficulties above, you're probably coding in a not standard / right way.
Remember that VBA is an event driven language, and you would be better using it's strenghts rather than fighting against them.
As a final word, if this is just a casual coding, I suggest you using a global variable and make de Code Behind Form have set it up on control's change event.
If you're not sure what I mean, please leave a comment and I'll try to explain it better.
And, if you don't mind, let us know more about your starting code to get better answers.
